This fixes a problem where applications could ask the location
manager to do very heavy-weight things (like... say... update
location every minute), which would get accounted against the
system instead of the application because ultimately it is the
system making the heavy calls (wake locks, etc).
To solve this, we introduce a new class WorkSource representing
the source of some work. Wake locks and Wifi locks allow you
to set the source to use (but only if you are system code and thus
can get the permission to do so), which is what will be reported
to the battery stats until the actual caller.
For the initial implementation, the location manager keeps track
of all clients requesting periodic updates, and tells its providers
about them as a WorkSource param when setting their min update time.
The network location provider uses this to set the source on the
wake and wifi locks it acquires, when doing work because of the
update period.
This should also be used elsewhere, such as in the GPS provider,
but this is a good start.

Rather than polling for events from the native code in an event thread,
we now require the GPS HAL libraries to call our callbacks from a thread
that is registered with the JVM to call directly into Java.
This eliminates a thread from our code and removes one step in the chain
of message passing from the GPS to the Location Manager client.

Use MS-Assisted mode for single shot GPS fixes if it is supported.
Add finer grained control over accuracy to the android.location.Criteria class
and location criteria logic from LocationManager to LocationManagerService

GpsLocationProvider: Store new Location before onGpsStatusChanged is sent
Telephony: Add PUK MMI code support for CDMA RUIM phones
Type Zero Sms should not be displayed/stored/notified.
Now we stop after one fix rather than waiting for 10 when requesting occasional
fixes to conserve power.

Rather than holding a wake lock the entire time the GPS is active, we now
hold it only when messages are pending for GpsLocationProvider's Handler
and rely on the lower level implementation holding a wake lock when calling
into the provider.
